Characteristics and application occasions of flame retardant and fire resistant power cables
1. NH - YJV: fire resistant cross-linked polyethylene insulated, PVC sheathed power cable
It can be laid indoors, in tunnels and pipelines, and can withstand certain laying traction, but the cable can not bear external force. Single core cable is not allowed to be laid in magnetic material pipelines. If it is necessary to bear the action of external mechanical force, steel tape armor shall be wound.
It is suitable for occasions with special requirements, such as large capacity power plants, nuclear power plants, underground railways, high-rise buildings, etc.
2. YJV: XLPE insulated, PVC sheathed power cable
It can be laid indoors, in tunnels and pipelines, and can withstand certain laying traction, but the cable can not bear external force. Single core cable is not allowed to be laid in magnetic material pipelines. If it is necessary to bear the action of external mechanical force, steel tape armor shall be wound.
3. Zr - VV: flame retardant PVC insulated, PVC sheathed power cable
It can be laid indoors, in tunnels, cable trenches, pipelines, flammable and severely corrosive places, but it can not bear external mechanical forces. If it is necessary to bear the action of external mechanical force, steel tape armor shall be wound.
Features: in case of open fire combustion, remove the fire source and automatically extinguish within 12s.
4. Zr - YJV: flame retardant cross-linked polyethylene insulated, polyethylene chloride sheathed power cable
It can be laid indoors, in tunnels and pipelines, and can withstand certain laying traction, but the cable can not bear external force. Single core cable is not allowed to be laid in magnetic material pipelines. If it is necessary to bear the action of external mechanical force, steel tape armor shall be wound.
Features: in case of open fire combustion, remove the fire source and automatically extinguish within 12s.
5. NH - VV: fire resistant PVC insulated, PVC sheathed power cable
It can be laid indoors, in tunnels, cable trenches, pipelines, flammable and severely corrosive places, but it can not bear external mechanical forces. If it is necessary to bear the action of external mechanical force, steel tape armor shall be wound. It is suitable for occasions with special requirements, such as large capacity power plants, nuclear power plants, underground railways, high-rise buildings, etc.
